I really want to have another baby. I think I might be pregnant again. I am 3 weeks late on my period, and I have always been on time. I had a miscarriage last year, but the doctor said I am in great health. My hormone levels are fine, and I don't have any symptoms of menopause yet. I know I am at high risk for miscarriages, because of my age. Is there anything I can do to carry this baby full term. I exercise, eat right, I'm not overweight, and I take vitamins daily. I don't drink or smoke.. My husband would really like another child, since our other children are grown and out of the house. We both miss the care of a baby.
